Application ned August 24, 15975 To ctZZ whom if vnu/y concern:

Be it known that I, HENRY TEssEYMAN, a i

ton, in the county of Montgomery and State ful Improvements in Truck andBody Bolsters for Freight and Passenger Cars; and I do hereby declarethat the following is a full,

My invention relates to improvements in truck and body bolsters forfreightv and passenger cars, its object being to so construct suchbolsters as to reduce the cost thereof and increase their durability,andwith such ends in view'the invention consists in certain novelclaims, and shown in the accompanying drawin Which- Figure 1 is a brokenperspective'view of theV invention, showing the relative positions ofthe two bolsters and 'the floor-sills of a carV mounted onthe'body-bolster, one half being shown in full and the other halfA insection through the longitudinal center of the bolsters; and Fig. 2, abroken perspective view the separate sections of the transom-bolstersare united.

Similar letters and figures indicate corresponding parts in thedrawings.

Each bolster is composed principally of two iron or steel channel-bars Aand B, the top bar A of the upper or body bolster being straight and thelower bar B being so formed center it is parallel with the top bar, andthen angles upwardly from the center to the end parallel portions, whileboth sections 'fof the lower or truck bolster are formed like the lowersection of the body-bolster. The edges of the side flanges 1 of thechannel-bars are brought together, Ornearly so, at their ends, where thetwo sections are firmly bound together by filling-blocks O, preferablycast and cored out on the insideto reduce their weight, in the mannerhereinafter explained. On the top and bottom of these blocks are formedan- -shown in Fig. 2.

nular collars or bosses 2, and on two opposite Serial No. 649,318. (Nomodel.)

ltion of theV ribs being to contribute strength to the hollow structure,through which holes 6, 7, and 8 are cored or bored,'as more clearly Oneof the filling-blocks is placed between the sections at -each end of thebolster, the sides 1 of the channel-bar sections overlapping two sidesof each block. Holes 9 are pierced through the iiat surface lO vof eachof the channel-bar sections to engage the annular collars 2 of thefilling-blocks, and the'side anges 1 are cut away to engage and to coactwith the lugs 8 in resisting the end strain on the saidside anges..

The side sills of the car-body are represented by the letter D and theintermediate sills' by the letter E, and they rest on the body- 'bolsteras shown.

Bolts 11 extend from the under side of the 'of each bolster VVbetweenthe ends thereof and which are bound firmly together by bolts 13, 14,'and 15, the bolts 13 passing up through `the sections, thedistance-posts, and the outside intermediate sills, while the bolts 14perform the same function in connection with the two center sills andthe further function of securing a center-bearing plate G to the Vunderside of the body-bolster, and the bolts 15 extend through the twosections of the truck-bolster, the intermediate posts F thereof, andthrough a center-bearing plate H,

mounted on the upper side of the bolster, and bind the said parts firmlytogether. The center bearing is composed of two parts I J, which are ofusual construction. An ordinary kingbolt K passes through both bolstersand IOO through the center bea-ring in the customary manner.

Side bearings L M are secured to the bolsters, as shown in Fig. l,although they may be otherwise constructed and arranged, as may also thecenter bearings, on which the body bolster rotates. The usual form ofchafe-plates are bolted to the sides of the truck-bolster, at the endsthereof, by bolts which extend through the holes 8 in thefilling-blocks.

It will be observed from the foregoing description of my improvedbolsters that they are of simple construction and of light weight inproportion to their required strength.

Having thus fully described the invention, I claiml. A bolster forrailway-Cars consisting of two channeled sections bent to desired shape,filling-blocks located within said sections, at the ends thereof, bossesformed on the top and bottom of said filling-blocks to engagecorresponding holes in the fiat surfaces of said sections, and meansforrigidly securing said sections to said filling-blocks, substantially asset forth.

2. A bolster for railway-cars consisting of two channeled sections bentto desired shape, filling-blocks located within said sections, at theends thereof, bosses formed on the top and bottom of said filling-blocksto engage corresponding holes in the fiat surfaces of said sections,means for rigidly securing the fiat surfaces of said sections to saidfillingblocks, and lugs or bosses formed on opposite sides of the latterto engage cut-outs in the side fianges of said channeled sections,substantially as set forth.

3. In truck and body bolsters for railwaycars, the combination of atruck-bolster and a body-bolster, each composed of two channeledsections bent to desired shape, fillingblocks located within saidsections at the ends thereof, bosses formed on the top and bottom ofsaid filling-blocks to engage corresponding holes in the fiat surfacesof said sections, means for rigidly securing said sections to saidfilling-blocks, and side and center bearings located between saidbolsters, substantially as set forth.

4. In truck and body bolsters for railwaycars, the combination of atruck-bolster and a body-bolster, each composed of two channeledsections bent to desired shape, fillinghlocks located within saidsections at the ends thereof, bosses formed on the top and bottom ofsaid filling-blocks to engage corresponding holes in the flat surfacesof said sections, means for securing the flat surfaces of said sectionsto said filling-blocks, lugs or bosses formed on opposite sides of thelatter to engage cut-outs in the side anges of said channeled sections,and side and center bearings located between said bolsters,substantially as set forth.

Vitn ess my hand to the foregoing specification on this 21st day ofAugust, 1807.
